Newage Stamford AVR AS440

AS440
Introduction:
The AS440 ( + Kit replaces SX440 ) is a half-wave phase-controlled thyristor type Automatic Voltage Regulator and forms part of the excitation system for a brushless generator. In addition to regulating the generator voltage, the AVR circuitry includes under-speed and sensing loss protection to ensure safe, reliable control of the generator. The Propose employs surface mount technology (SMT) for high integration of features in a minute footprint AVR.

Positive voltage build up from residual levels is ensured by the use of proficient semiconductors in the power circuitry of the AVR. The control and voltage sensing circuits have separate terminals, allowing the excitation power to be resulting directly from the stator winding for necessary applications or from an auxiliary winding if sustained short circuit performance is essential. Which is linked with the main stator windings and the exciter field windings to offer closed loop control of the output voltage with load regulations of +/- 1.0%

Features include:
*Stability adjustment *Optimum response selection
*Under frequency roll off adjustment *Droop adjustment
*Trim adjustment
